Application led January 4, 1919.

To all whom it may concern Be it known that l, lnNnsT ALSCrrULnR, a citizen or the United AStates, and residing at St. Louis, Missouri, have invented the new and useful improvement in Battery llandlainps, of which the following is a specification.

rlhis invention relates to battery hand lamps.

ln a battery hand lamp having a metallic battery-receiving casing, diiiiculty is experienced in providing` a simple construction whereby the circuit may be closed through the lamp and battery.

@ne oi the objects oi' this invention, therefore, is to provide a battery hand lamp having a metallic battery-receiving casing, which is so constructed and arranged as to permit simple but substantial connections to .be made which are not liable to short circuit.

ln a battery hand lamp, the lamp itself is usually mounted in a base which forms the reflector andthe battery terminal engages directly with one of the terminals (usually the central terminal) of the lamp. Nith such a construction when the hand lamp is subjected to shocks, as when it is allowed to drop, the impact will frequently cause breakage of the lamp iilament.

Another object of this invention, therefore, is to provide a yielding contact between the battery and the lamp terminals which will act as a shock absorber and thereby prevent breakage of the lamp filament, which is adapted for application to any standard form of hand lamp.

Another object is to provide a hand lamp having a novel switching arrangement which is simple in construction, e'ective in its action and cheap to manufacture.

Further objects will appear trom the detail description, taken in connection with the accompanying drawing, in which:

Figure 5 is an enlarged detail of Figure 1, showing the shock absorber;

Figure 6 is a View similar to Figure 5, but showing another embodiment of this invention; and

Figure is a view similar to Figure 4, showing.' still another embodiment.

Referring to the accompanying drawing, and more especially to Figures 1, 2 and 3, 1 designates a casing of metal having enlarged threaded ends 2 and 3, which are adapted to receive threaded rings 4 and 5 respectively. rlhe ring 4 has a closed end 6, carrying a spring? adapted to bear against and make contact withthe end terminal of a battery 8 carried by the casing, it being understood that there are two or more batteries arranged end to end in a single covering or carton of paper or other light insulating material.

Arranged at one end ofthe casing is a reflector 9 which has a threaded thimble 10, adapted to receive the metallic terminal 11 of a. lamp 12. rThis reflector has a flange 13, adapted to engage vand make contact with a metallic ring 14 spaced from the end 3 by a ring 15 of insulating material. The rings 14 and 15 are threaded to correspond with the threaded end 3, so that the rings are arranged in nested relation within the end 3 of the casing, but whereby the contact ring 14 is insulated from the casing. The insulating ring;v 15 is prefer` ably provided with an end flange 16 to form a stop and also insulate the end 3 Mounted on the flange 13 of the reflector is a lens 17 which is retained in place by a lange 18 of' the ring 5. rl`he reflector vange 18 is ot a smaller diameter than the ring 5 so that it will not contact with the ring, and the reflector body makes a snug lit with the contact ring' 14, this contact ring being preferably split as shown in Figure 2 so as to make a firm mechanical connection with the insulating ring 15 in order that lthe Contact ring may be firmly retained in position. l

Mounted inside of the casing is a base 19 of insulating material, which is secured to the casing in any suitable manner as by rivets 20. This base carries a Contact 21 connected by an insulated lead 22 with the contact ring 14. The contact 21 is positioned in y button 26.

an enlargedaperture 23 formed in the casing so that this contact will be insulated from the casing. Mounted on the outside of lthe casing'in any suitable manner is a base for al circuiti-closing switch which may be formed of sheet metal, and has a struck-up portion forming a housing 24 for theJ switch elements. One of these elements has the form of'a flat spring and carries at one eX- tremity an operating button 26 and a contactA y25 adapted upon fleXure of the switch member by means of the button 26 to contact with the head ofthe rivet 21. The secondyswitchmember is mounted underneath the irst and secured in position by overlapping flanges extending inwardly from a manipulative member 28 mounted outside of the housing 24. These flanges extend through slots in the housing 211, embrace the edges of the first switch member and, passing through notches in the sides ofthe second switch member, are folded over 'underneath said second member to secure it in position. This construction is clearly shown in Figures 3 land 4. The second switch member is provide'd with a curved contacting terminal 27 which' is adapted to make contact with the head of the rivet 21 when this member is slid forward along the housing 24C by movementfof the manipulative member l28. Tt will-be seenvthatV this providesy two ways of closingthe circuit.v Momentary contact may ybe made bypressing the button 26 so as to bring the Contact 25 into engagement with the rivet 21, or the member 28 may be moved forward carrying with it the contact 27 into engagement with the rivet 21 for the same purpose.

When either of the contacts 25 or 27 is moved into engagement with thel contact 21, th@j circuit will be closed through the contact on the casing, ythe contact 21, the lead 22, the contact ring 14, the reflector 9, the lamp terminal 11, the lamp filament, the lamp terminal 30, Ithe batteryv 8, the spring 7 the c'ap`6 Aand the casing 2. Tt will be noted that the reflector, forming the lamp carrying base,fis vinsulated from the metal casing and that this isobtained in a simple and effective manner through the provision of the contact ring insulated from the end of the casing by the simple insulating ring. This not only furnishes a simple and effective structure, but also prevents short circuiting of the lamp by extraneousconnections, for the reason that the circuit can only be closed by movement of the switch. It will be seen,

therefore, that withthis construction, it isk possible to obtain in a metal casing structure eithera duration or flash Contact, the former being obtained by movement of the thumb piece 28 and thev latter by movement of the Referring to Figures 1 and 5, the threaded nipple 10 has mounted vthereon'a base pro` vided with means for connecting the central lamp terminal 3() with the batteryterminal 29. This base comprises a disc 31 of insulat ing material, which is internally .threaded to take over the nipple 10 and which carries a casing 32of metal havingr a flange portion u through the bottom 34:, the spring 35 and thev follower 36. ldli'ththis construction th'ereis a yielding Contact connectionfrom the battery to the lampterminal. Tt will further be noted that the support l32 being mounted on and yinsulated from the reflector, all shocks will be absorbed by the reiiec'torwhile such 'shocks will not be transmitted to the centrallamp terminal on raccount ofthe yielding contact connection which absorbs the shock. y n f A In theconstruction shown in Figure 6, the yielding 'element comprises a plate 38 retained in the bottom 311 of the support 32 by the crimped portion 37, and this plate has a tongue 39'struck u'p therefrom and adapted to bear against the lamp terminal 30. It vwill be understood, ofcourse, that the plate 38 is of spring 'metal so that the tongue 39 will yieldingly bear against the lamp terminal and thus-.absorb all shocks and ars. l, C In the construction shown in Figure 7, the insulating disc 31 has securedV thereto byy rivets 40 or otherwise, a frame or stirruplll of spring met-al `providing a cross piece 42, adapted tocontact with the terminal 29 of the battery and provided with one or 'more struck up portions/43 which arey adapted to bear against the lamp terminalBO. Y

This finger or these fingers is or are each tached at one end only, while the other endr is` free, and where twofingers are used` they extend in opposite directions. These fingers, therefore, rbear yieldingly against the Vlamp terminal so as `to absorb and cushion all shocks and jars. i y Y Y It will be noted that the casing or bumper is' a metallic one, Vandnot onlyengages but also 'makes Contact with vthe battery termi! nal, while the yielding Contact engaging the lamp terminal has a direct electrical connection with the bumper and, therefore, vwith the battery terminal so as, to provide a permancnt connection vbetween the battery and the lamp. n'accordan'ce with this'invention, therefore, a which can be applied'to any standard-form of han d lamp or flash light for by the simple removal of the reflector, thisshockahsorb'er can be applied to the nipplethereof, 'andl` shock absorber is provided 'incarna l.
